The purpose of this study was to determine the relationship between video game addiction and the need to socialize in adolescents. The research design used descriptive correlation with cross-sectional approach with a population of 67 respondents. The sampling method using Cluster Random Sampling obtained a sample of 60 respondents. This research was conducted by giving questionnaires to teenagers who were playing video games to find out the level of video game addiction and to know the level of social needs. The results of this study were analyzed using the Spearman Rho Correlation test, it was found that video game addiction in adolescents was mild addiction as much as 28.3%, moderate addiction as much as 28.3%, and severe addiction as much as 43.3%. While the need for socializing results obtained low needs of 20.0%, medium needs of 55.0%, and high needs of 25.0%.

Abstract

The agricultural sector is one type of work that has a high risk for workers. Extreme environmental conditions and the way and use of technology in managing land that is still traditional compared to other regions determine the level of health and safety of farmers. Ergonomics is the science, art and application of technology to harmonize or balance between all facilities used both in activity and rest with all abilities. The sampling technique used is the simple random sampling method. This study is a cross-sectional study. The population in this study was 80 respondents, a sample of 67 respondents. (0.05) which shows that there is a relationship between ergonomic position and low back pain in Karang Tengah Village, Jember Regency. This research shows that the role of occupational health nurses or Occupational Health Nursing (OHN) in agriculture must be increased

Abstract

Introduction: Diabetes Mellitus (DM) is a chronic disease (CD) in Indonesia that contributes to high mortality. This disease poses a limitation to self-care. Good self-care prevents complications and improves the quality of life. Self-care application (SCA) is a way to increase understanding of Type 2 Diabetes Mellitus (T2DM) clients and their families to improve the quality of care and good management of T2DM clients. Objective: To determine the effect of SCA on improving the quality of care and management of T2DM clients which include blood sugar levels, nutrition management, activity/ exercise management, self aesthetics, and personal hygiene. Methods: A quasi-experimental design with a non-equivalent control group design. The population of this study was patients with type 2 diabetes with a total sample size of 50 patients with type 2 diabetes who were evenly divided into 2 research groups. The sampling method used was proportional sampling. The interventions are in the form of SCA with training and mentoring patterns of T2DM clients and their families. Data analysis using independent t-test. Result: The application of self-care had no significant impact on blood sugar stability (p 0.540), was able to improve the quality of nutritional management (p 0.018), improve activity/ exercise management (p 0.000), improve self-esthetic behavior (p 0.000), and increase personal hygiene behavior (p 0.000). Conclusion: Improving the quality of care and management of T2DM due to SCA is directly related to the understanding and awareness of T2DM clients.

Abstract

Rice is one of the main crops produced by agricultural commodities which is staple food of most Indonesian people. The availability of rice is needed to anticipate the emergence of problems in the future such as population growth, changes in seasons, or as an export commodity. Estimation of rice availability in the future can be done by forming a mathematical model, where the mathematical model used is the Verhulst logistic model. The differential equations in the Verhulst model are first solved using Runge-Kutta method to obtain four initial solutions to be used in finding approximate values using the Adams-Bashforth-Moulton method. After obtaining an approximate solution, a comparison of the accuracy based on error is carried out. The Verhulst model with a step size and carrying capacity rice harvest at Jombang Regency limited 500,000 tons, 600,000 tons, and 700,000 tons, obtained rate error values from numerical solution of Adams-Bashforth-Moulton method is 3.35%, 3.39%, and 3.36%.
